So, i need to find the value of b but im very confused on how to! can someone me?

b = 78°

The angles at a point sum to 360°

that is 45 + 237 + b = 360

282 + b = 360 ( subtract 282 from both sides )

b = 360 - 282 = 78°

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
